Description

The proposed utility model is designed to automatically create a supply of water from a water supply system in the presence of pressure in it and allowing the use of stored water when pressure is reduced or absent in the water supply network.

It is known that in many settlements, especially in the summer, due to the large withdrawal of water, a regulated water supply is introduced. As a rule, at night, water is supplied uninterruptedly and fills the water supply network completely. Water consumers are forced to create a supply of water for the day at night. This creates discomfort to the population and adversely affects human health.

This is especially true for residents of apartments of multi-storey buildings, where residents are deprived of the possibility of cooking and fulfilling sanitary and hygienic needs.

Known water supply stations providing water to the consumer during a stop of the central water supply.

The device [1] comprises a pump with a reservoir on the pressure line and a system for replenishing the reservoir with air. The system of replenishing the tank with air is equipped with an air supply valve with a hydraulic conduit, a control valve with an actuator and a liquid level sensor in the tank, while the suction line of the pump is connected through an air supply valve to the atmosphere, the hydraulic actuator is connected to the pressure line through the control valve, and the actuator of the latter is connected to the sensor level.

The disadvantage of this device is that the installation is complicated, and therefore cannot be used in a small city apartment, which reduces the efficiency of its work.

The water supply station [2] contains a container with a manometer, a pump, valves, suction and discharge pipelines.

A pipe has been introduced into the rarefaction zone of the pump, one end of which is located in the rarefaction zone, and the other communicates with the outer surface.

This station is similar to that described above, it is also complex and not intended for installation in a small apartment.

Water in the tank is saturated with air, its pressure

decreases and the efficiency of the station also decreases.

Water supply station [3] - prototype, contains a water tank, pressure gauge, pump, control unit. The water tank is combined with the air tank by introducing a movable dividing partition into the water tank, which divides the water tank into an air cavity and a cavity filled with water, and the partition prevents the saturation of water with air and during operation of the station, the partition moves together with the medium interface water-air. The partition is made in the form of a disk or piston.

The disadvantage is that the water tank with such a partition cannot work in a horizontal position, which reduces the efficiency of the installation.

The technical result of the proposed options for a utility model is to increase the efficiency of the water supply station and expand the arsenal of technical equipment for a similar purpose.

The technical result according to option 1 is achieved by the fact that in a rigid cylindrical water tank, placed

sealed elastic container fixed at the top of the rigid container. At the attachment point, an elastic container is connected to a sleeve for supplying compressed air. An elastic container repeats the geometry and internal dimensions of a rigid container, is a water-air separator, and extrudes water from a rigid container to a consumer.

The pressure network filling the station with water is equipped with a non-return valve that prevents the water from escaping from the station when this network is disconnected or the pressure in it drops.

Elastic capacity prevents the dissolution of air in water of a rigid capacity. During installation, an excess air pressure of ~ 0.2-0.5 kg / cm2 is created in an elastic container, for example, with an automobile pump. The station, after taking water from it, is automatically replenished with water from the pressure network.

The above technical result allows the water supplying station to service the gas water heater which operates only at increased pressure in the water supply system, that is, the consumer may have hot water, which increases the efficiency of the station.

However, such a water supply station is not efficient enough in apartments where regularly low pressure in the water supply.

The station will store a small volume of water, due to the fact that the volume of water stored in it directly depends on the pressure in the water supply, since a part of the water tank is occupied by an elastic tank with air.

Option 2 of the station aims to increase the volume of stored water. This technical result is achieved in that a rigid cylindrical container is located horizontally in the corner between the wall and the ceiling.

The pressure network is also equipped with a check valve.

Inside the elastic container, in its neck, a float shut-off valve is installed, which communicates through the pipe with the external environment and bleeds air from the elastic container when filling the rigid container with water.

The water supply station according to option 3 is a counter-grouping of rigid containers, while one elastic tank is equipped with a float valve connecting its internal cavity to the atmosphere through a saddle and

sleeve, and another elastic container provided with a sleeve for supplying compressed air. The pressure network is also equipped with a check valve. This option pursues the goal of creating a low-pressure water supply in one tank and a high-pressure water supply in a second tank, which significantly increases its efficiency.

The technical result is achieved by the fact that rigid water containers are connected in the lower part by an adapter, and in the upper part one elastic tank is equipped with a shut-off float valve communicating with the atmosphere via a flexible pipe, and an excess air pressure is created in the second elastic tank during installation.

In option 4, the volumes of the counter-grouped two rigid and two elastic containers are connected using adapters so that one adapter connects the water tanks and the other connects the air tanks. The adapter connecting the air tanks is equipped with a fitting for the general air supply during installation and connection, through a flexible sleeve, of the pressure gauge.

The pressure network is also equipped with a check valve.

This option allows you to increase the amount of stored water, which also increases the efficiency of the station.

Common essential features of the prototype and the claimed options for a utility model are:

1. The presence of a rigid container under water.

2. The presence of an air cavity in the water tank.

Distinctive features are:

1. The presence of an elastic tank under the air, placed in a rigid tank under the water.

2. The horizontal location of the rigid and elastic containers.

3. The presence in the elastic tank float shutoff valve.

4. The possibility of linear oncoming grouping of two containers for water and air.

Analysis of the proposed utility model (options) and prototype shows that the proposed water supply station (options) is new and industrially applicable, that is, it meets the conditions of patentability.

The essence of the utility model will be described in more detail below.

Figure 1 presents a schematic drawing of a water supply station made according to option 1, figure 2 - option 2, figure 3 - option 3 and figure 4 - option 4.

The water supply station according to option 1 consists of: a rigid tank of cylindrical shape 1, with a water supply nozzle in the lower part 2, plugs 3 and 4, an elastic tank 5, repeating the shape of the tank 1, and hermetically fixed in the area of the plug 4. There is a fitting on the plug 4 (not shown in Fig. 1) for connecting a sleeve 6 through which compressed air is pumped into an elastic container during installation and a pressure gauge 7 is connected.

Inside the elastic container 5, in the lower part, there is a food antiseptic, for example, water with silver ions and the food coloring 8 dissolved in it, with a volume of 0.5-1.0 liters. Figure 1 also shows a pressure network with a valve 9, a non-return valve 10, a pressure gauge 11, and a consumption network 12 (for example: kitchen, bathroom, etc.).

Figure 2 presents a variant of the station, where the water tank 1 is located horizontally, for example, in the corner of the wall and ceiling.

The container can be closed with a decorative overlay. In the proposed embodiment, in the top cap 3 there is a seat 13 ending in a sleeve 14. The seat 13 is closed by a float valve 15. The sleeve 14 is designed to supply compressed air during installation, to straighten the elastic container inside the rigid, as well as for emergency discharge of water into the sewer during failure of the valve 15 and rupture of the walls of the tank 5 during operation.

Figure 3 presents a variant of the water supply station, where the rigid cylindrical water tanks are grouped counterclockwise in one line. In the proposed case, the left elastic tank is equipped with a float valve 13, 15 (see figure 2), connecting it to the environment through the sleeve 14, and the right tank is equipped with a sleeve 6, for supplying compressed air and connecting the pressure gauge 7. Both containers 1 are connected tight adapter 16.

Figure 4 presents a variant of the water supply station, where the rigid containers 1 are connected by an adapter 16, and the elastic containers 5, an adapter 17 with a fitting 18 for connecting the sleeve 6. In this case, the containers are located during installation as shown in

figure 4 - water at the bottom, air at the top.

Station option 1 operates as follows. Compressed air with a pressure of 0.2-0.5 kg / cm2 is supplied to the elastic container 5 through the sleeve 6, which is controlled by a pressure gauge 7, which subsequently acts as a water level sensor in the container 1. The elastic container 5 can be made of elastic polymer material, which is allowed contact with food (in this case, water). Then open the valve 9 and through the check valve 10, when the valves are closed 12, water is supplied, through the nozzle 2 into the rigid tank 1. Using the pressure gauge 11, the working pressure of the water in the pressure network is controlled. The elastic container 5 takes the form shown in Fig. 1. The liquid 8 located inside the elastic container 5 reduces the friction of the inner walls of the container when the water level in the rigid container 1 changes, and the dissolved food coloring, when the walls of the elastic container 5 break, gets into the water of the container 1 and signals a malfunction.

The air in the elastic container will partially dissolve in the liquid 8, with increasing pressure (filling

tank 1 with water) and stand out from it, with a decrease in pressure, which allows to increase the volume of water stored in tank 1.

When taking water from tank 1, tank 1 is automatically replenished with water, through a constantly open valve 9 and check valve 10. If the pressure in the water supply network decreases, the water of the water supply station is locked by check valve 10. Automatic pumping of the station increases its efficiency, that is, ensures the achievement of a technical result.

According to the readings of pressure gauges 7 and 11, one can judge, respectively, the water level in the tank and the presence of pressure in the water supply. The stored energy of compressed air in the elastic tank 5 acts as a spring for pushing water into the local water supply system and provides the pressure necessary for the working state of the gas column, which automatically turns off when a certain lower threshold value of the water pressure in the system is reached. It also increases the efficiency of the plant, as the consumer is provided with hot water.

All this works to achieve a technical result.

The operation of the station according to option 2 (see FIG. 2) differs from that described above under option 1 in that the rigid tank 1 is located horizontally, for example, under the ceiling of the building, which provides hydrostatic pressure of the water in the valves 12, corresponding to the height of the tank 1. from it, to the cranes 12 will flow by gravity as follows. During installation, the elastic container 5 is straightened inside the container 1 with a small pressure of compressed air, for example, by a car pump, through the sleeve 14. Then, the container 1 is filled with water, opening the valve 9 of the pressure network. As soon as the water reaches the level shown in Fig. 2, the float valve 15 closes the seat 13. Due to the fact that the elastic container had, through this seat 13, a message with the environment, almost all of the air was squeezed out. This ensured its almost complete compression, which allowed to store the maximum volume of water. At the end of filling the tank 1 with water, closing the check valve 13, ensured the tightness of the elastic tank, with some air in it.

A small part of the air remaining in the elastic tank after closing the float valve will be compressed by water pressure and subsequently, when the pressure in the water supply changes, it will automatically partially update the water stored in tank 1.

This means that the water in the tank 1 will not stagnate in the same way as in the first embodiment. The elastic capacity prevents the dissolution of the remaining air in the water, as well as contamination of the water with bacteria, dust and odors.

Such a station cannot interface with a gas column, but it accumulates the maximum volume of water, which also increases the efficiency of the station, that is, it ensures the achievement of a technical result.

The operation of the water supply station according to option 3 (see FIG. 3) differs from the options described above in that both options are combined into a single device, where the rigid containers 1 are arranged counter and horizontally, and are connected to each other using an adapter 16. This option is so it is also necessary to place it at the top, in the corner between the wall and the ceiling, and you can close it with a decorative panel of the corresponding design.

The station is filled with water as follows: when the tap 9 is open, and there is pressure in the pressure network, water will begin to fill the left tank 1, squeezing air from the elastic tank 5 located in it, through the seat 13 of the float valve 15 and the sleeve 14 into the atmosphere. When the left tank is filled with water to the level shown in Fig. 3, the float valve closes and the air remaining in the elastic tank begins to be compressed by the water filling the tank 1. When the pressure in the left tank 1 increases, to the level of air pressure in the right elastic tank created initially during installation of 0.2-0.5 kg / cm2, water will begin to fill the right tank 1 as well. When the pressure in the tanks 1 is equalized with pressure in a pressure head network, their filling with water stops.

When the pressure in the pressure network decreases, the check valve will not allow the water stored in tanks 1 to return to the pressure network.

The use of water stored in tanks 1 in the absence of pressure in the pressure network and the open valve 12 will occur in the reverse order, that is, first the water will be squeezed out of both tanks 1 in proportion to the volume

compressed in elastic containers of air. After all the water has been squeezed out of the right tank 1 (the volume of compressed air in it is many times greater than the volume of compressed air in the left tank), the water level in the left tank 1 will begin to decrease. When the level falls below the one shown in figure 3, the float valve will open and Further, water from the left tank 1 to the taps 12 will flow by gravity due to the difference in heights.

The combination of the 1st 2nd option significantly increases the efficiency of the station, ensuring the achievement of a technical result.

The work of the water supply station according to option 4 (see FIG. 4) is a counter linear grouping of two stations of the first option located horizontally, where the cavities of the elastic containers 5 are interconnected by an adapter 17, with a fitting 18, and then a sleeve 6 with a pressure gauge 7 (in FIG. .4 not shown). Through the sleeve 6, both elastic containers 5 during installation are filled with compressed air to a pressure of 0.2-0.5 kg / cm2.

The adapter 16 combines the cavity of the rigid containers. Through valve 10 and fitting 2, after opening valve 9, both

rigid containers 1 are filled with water.

The proposed version of the water supply station has a large supply of water and the stored energy of compressed air, sufficient for the operation of a water heating gas column. It is advisable to use such a station in large families where a large supply of water is required, with its unstable supply.

All options can reduce the load on the water supply network during peak hours, as consumers will use pre-stored water. All options increase the efficiency of the water supply station and expand the arsenal of technical equipment for a similar purpose.

The device is new and industrially applicable. It can be made in the conditions of mechanical workshops.
